Research on Measuring Method of Locked rotor On-line Test for Single phase Asynchronous Motor

In the computerized automatic test system of small asynchronous motor, the research on method of rapid measuring locked rotor performance is always an emphasis. Thinking about single phase asynchronous motor, this paper introduces the principle and property of the dynamic test method of locked rotor experiment first. Then a new method called Single Winding Energization is presented. Through research and practice, this method is valid for measuring the current and power of single phase asynchronous motor during locked rotor experiment under steady conditions without braking, and is more suitable for the computerized automatic test system.
